− | According Tomassini et al.,<ref name=Tomassini /> the interpreted transport and sedimentation processes were strom events that put particles suspension and subsequent decanting. The absence of [[bioturbation]], dark colors and bindstones suggest a low rate of sedimentation, low energy and low oxygen environment. | + | According Tomassini et al.,<ref name=Tomassini /> the interpreted transport and sedimentation processes were strom events that put particles suspension and subsequent decanting.
